Quadrans
The Quadrans is a Roman coin, a quarter of an ace, which is the smallest nominal of the Roman monetary system since the late Republic.
In the early Republican period, the time of the Aes Grave currency, the coin was marked with three points. Later, the markings accounted and the coins were struck in copper / bronze. An exception are the imprints under the Emperor Nero, who had hit his Quadrans on brass. The average weight of 2.8 g was Quadrans
The reverse of the coin was, as with Roman bronzes usual, marked with "S C" for Senatus Consulto, which translated means as much as by decision of the Senate. It would have, however, acted more to a gesture in this name, because de facto sovereignty was the coinage solely with the Emperor.
The Quadrans was - as the semis - not particularly distinct impression from the beginning and disappeared mid-2nd century completely out of the picture. In retail, therefore we resorted to early with quartered Asses or foreign small bronzes and urban brands.
